I found one of these last year and the other this year at estate sales 15 miles apart.  One Phillips and the other flat. Strongly magnetic.  I like the knurling on the handles.  No makers marks on either. 

I didn't know there was such a thing as a machinist screwdriver but I like screwdrivers with reversible bits.  Very handy.

Well, yeah.  You don't want your machinists to fall apart due to lack of maintenance
